It was cold and very foggy, the temperature was around -10 degrees Celsius. It was down to the snow-making, as dozens if not hundreds of cannons were making the course for the World Cup and elsewhere. When the clouds began to break, there were rainbow colours in the sky and a halo spanning 360 degrees.

He captured a lunar halo combined with a full parhelic circle, two sundogs and a 120 parhelion, which you can see in the beautiful photo below (it's the glowing spot aligned with the parhelic circle.)

These types of events rarely happen together—the sun light needs to refract on millions of suspended hexagonal ice crystals under special meteorological conditions. Only on very rare occasions they all happen under the moon light. In this case, the crystals were produced by the snow machines in the ski station.

This drawing by NASA explains what you are looking at here:

One more reason to go up north, when these events can happen. The other one being auroras, of course.
